the two or more sets of condition assessment data comprising a first data type obtained using a first sensor type and a second data type obtained using a second sensor type;
after a pipe feature has been identified using one or more of the first data type and the second data type, selecting, using a processor, an image processing technique based on the pipe feature;
wherein the selected image processing technique modifies an interpolation technique used to process one or more of the first data type and the second data type associated with the feature; and
forming, using the processor, an image of the interior of the pipe by implementing the selected image processing technique.
